Is there a tape device at /dev/rmt/0mn? Post the output of "ioscan -kfnCtape".

You should first try to clean the drive, try another tape and check for write protection.

Try to make a backup, using tar or cpio, to test the tape drive and midia. If not write in a tape, you have a problem with you tape.

Hi,

On my experience, it could be either media problem or drive faulty. Try with tar command to read and write and verify both modia and drive is working or not.

Hi,

Another possiblity is that if you replace the drive online then kernel won't be able to detect the drive. or if you connect the drive with different scsi id (diff h/w path)
then you will get this error.

In this case you need to reboot the box or recreate the device file.
